Application fi led October 16, 1909. Serial No. 523,009.

To all whom it may concern:

Be it known that we, THOMAS IGNATIUS YOURELLE and JOHN BELLINGHAM, subjects/ of His Majesty the King of Great Britain and Ireland, and both residing at 215 Lambton Quay,Wellington, in the Provincial District of lVellington, in the Dominion'of New Zealand, have invented certain new and use ful Improvements in Ferroconcrete Construction of Buildings, of which the follow ing is a specification.

The invention relates to the construction of buildings having inner and outer walls of slabs .or plates, said walls being connected by; cross ties and the space between them wholly or partially filled by concrete.

The invention provides an improved form of reinforced slab or plate, means for connecting the inner and outer walls by ties, and apparatus for use when filling with concrete part only of the space between the walls.

Referring to the accompanying drawings; Figure l, is a perspective view of the corner of a building in course of construction, Fig. 2, a sectional plan of part thereof, Fig. 3, a perspective view of a slab, Fig. 4, a similar view of the reinforcement thereof shown independently, Fig. 5, a perspective view of a tie for connecting the inner and outer walls, Fig. 6, a similar view of a distance piece.

The slab according to our invention (as shown particularly in F ig.3) hasl edges 1 and 2 projecting'respectively from the bottom and side of the inner face and the edges and opposite end of the outer facet The slab appears as if it were composed df .two

equal slabs one upon and overlappingthe other. In the course of, manufacture, wire netting 5 is embedded in the slab which has also the angle iron 6 partly embedded in\ it.

The angle iron (see Fig. 4) i double cutin places and the portion between the cuts bent back to form a hook 7 which engages beneath the wire netting. The slab may have a facing 8 of sheet glass or may be rough east to represent stone.

The mode of employing the blocks fin a building is shown in Figs. 1 and 2. The inner and outer walls 29 and 30 respectively are built up with cement joints the edges of eachzblock on all sides overlapping or being overlapped by theedges of the blocks in immediate juxtaposition. The blocks are made intwo lengths so that a break of joint is ob- ,tained as in ordinary brickwork.

The inner and outer walls are connected a-rouncl tubular uprights 34 which may be used in the space between the walls for strengthening purposes.

The space between the walls may be en-/ tirely filled in with concrete as the erection of the walls proceed, or if desired stiffening pilllars of concrete may be formed at interva s.

What we do claim and desire to secure by Letters Patent of United'States is 1. A building block comprising" a slab composed of two equal rectangular portions of cemerit-like material integral y joined face-to-face with a top and end edge of one advanced above and beyond the corresponding top and end edge of the other; a wire netting extending from edge to edge of one of said portions parallel to the broad face thereof; an angle iron extending horizontally from end to end of the slab and having a vertical web in said last named portion and against said netting and provided with cuts forming tongues bent back and engaging beneath said netting, the horizontal web of said angle iron extending from said slab and being provided with small holes.

2. A building block comprising a slab composed of -two equal rectangular portions of cement-like material integrally t'oined face-to-face with a top and end edge of one advanced above and beyond the corresponding top and end edge of the other, a wir net ting extending from edge to edge of sai por-y tions parallel. to the broad face-thereof; an angle iron extending horizontally from end to end of the slab and having a vertical web in said last named portion and against said netting and provided with cuts formingtongues bent back and engaging beneath said netting, the horizontal web of said angle iron extending from said slab and being provided with small holes and horizontal tie rods having turned down. ends engaging in said holes and adapted to connect inner and outer Walls.

3. A building block comprising a slab composed of two equal rectangular portions of cement-like material integrally joined face-to-face with a top and end edge of one advanced above and beyond the corresponding top and end edge of the other; awire netting extending from edge to edge of one of said portions parallel to the broad face thereof; an angle iron extending horizontally from end to end of the slab and having a vertical Web in said last named portion and against said netting and provided With cuts Copies of this patent may be obtained for five centseaeh, by addressing the Commissioner of Patents,
